测定了微囊藻属47株细菌的16S~23S核糖体DNA内转录间隔区序列。构建的最大似然法和DNA距离树表明，微囊藻可分为三类。第一类包括有毒和无毒菌株，第二类只有有毒菌株，第三类只有无毒菌株。树的拓扑结构不一定与形态种的区别或藻胆蛋白的色素组成相关，并且一个基因可能有一个以上的形态类型。基于基因间隔区序列的系统发育分析被认为是了解密切相关物种和菌株之间关系的有效方法。(C)1999年欧洲微生物学会联合会。爱思唯尔科学公司出版。版权所有。
16S to 23S ribosomal DNA internal transcribed spacer sequences of 47 strains of the genus Microcystis were determined. Derived maximum likelihood and DNA distance trees indicated that Microcystis can be divided into three clusters. The first cluster included toxic and non-toxic strains, the second only toxic ones, and the third only non-toxic ones. The tree topologies were not necessarily correlated with morphospecies distinction or phycobilin pigment composition, and one genotype may have more than one morphotype. Phylogenetic analysis based on intergenic spacer sequences was thought to be effective for understanding relationships among closely related species and strains.
